Connecting to a Serial Interface
You connect 44-pin serial cables to serial connectors on ARN/DC adapter and
expansion modules. Each serial interface supports multiple WAN protocols at a
transmission rate of 1200 b/s to 2.048 Mb/s.
To connect to a serial interface:
1.
Locate the serial interface cable.
The serial expansion and adapter modules automatically configure the desired
electrical interface when used with standard keyed cables such as the
following, which are described in the Cable Guide:
2.
Connect the cable to an expansion module serial interface (Figure 1-8) or
an adapter module serial interface(Figure 1-9)
.
Figure 1-8. Connecting Serial Cables to an Expansion Module Interface
Connector numbering on expansion module serial interfaces begin with
COM3.
Note:
The Cable Guide refers to serial cables that transmit synchronous data
as “synchronous” cables.
